Both human hereditary spherocytosis (HS) and chronic myelogenous leukemia (CML) are life threatening.Herein we have reported the case of a woman with a combined disorder of HS and CML who underwent the matched sibling allogeneic stem cell transplantation.The complete donor erythroid cells were obtained.The red blood cell counts significantly improved throughout life comparing with pre-hematopoietic stem cell transplantation (HSCT).Reticulocyte counts normalized,and BCR-ABL was cleared away.The total bilirubin level was also corrected in this recipient.Our case is a rare example with a combined disorder of HS and CML following allogeneic stem cell transplantation.HS was not a contraindication for patient in the matched sibling transplant setting.
